Separated mine in high school playing football. Played the next game 7 days later. To this day it isnt the same. If I sleep and leave my right arm up above my head my arm falls asleep.
So the right answer is hit the mountain and be careful when you think you can take a little spill and not be in agony. Without surgery, which isnt necessary, separations dont "repair" themselves and go back to where you were before.
